Surface tension and surface energy

Question

A vessel, whose bottom has round holes with diameter of 0.1mm, is filled with water. The maximum height to which the water can be filled without leakage is
(S.T. of water =75 dyne/cm, g =1000 cm/s²)

Moderate

A

100 cm
B

75 cm
C

50 cm
D

30 cm

Solution

$h = \frac{2 T}{rdg} = \frac{2 \times 75}{0 .005 \times 1 \times 10^{3}} = 30 cm$
